UNITED STATES PATENT OFFICE MERRITTPEOKHAM, OF UTICA, NEW YORK.

BASE-BURNING STOVE- Specification forming part of Letters Patent No.106,503, dated August 16, 1870.

To all lwhom it may concern:

Be it known that I, MEERITT PEGKHAM, of Utica, in the county of Oneidaand State of New York, have invented a new and useful Improvement inMagazine-Stoves; and I do hereby declare the following' to be a full andcorrect description of the same, sufcient to enable others skilled inthe class to which my invention appertains to fully understand and usethe same, reference being had to the accompanying drawing which makespart of this specification, and in which- Figo re lis a frontelevationof my improved magazine-stove 5 and Fig. 2 is a vertical section of thesame.

Like letters of reference indicate like parts in both figures.

The nature of my invention consists in providing the magazine of abase-burning magazine-stove with any suitable number of openings,provided with covers, which act as dempers, and through which a pokermay be introduced to clear the coal in the magazine if it gets fast.

In the drawing, A may represent the magazine, opening conically at itslower end, while the upper end is closed by a feed-cover, B. C is thegrate, and D D the lines, which latter extend from the re-chamber Eupwardly into the smoke-chamber F, in which the stove-pipe is secured,at f.

Gr G are circular openings formed in the magazine, and provided withdoors or swinging covers H. The openings may be square, if desirable,and any suitable number may be used. By opening any or all of theopenings either entirely or only partially, a downward draft is createdthrough the coal in the magazine, and as the latter is principallyburned in and above the base of the magazine, the smoke and gasesescaping from the igniting coal are forced into and through the cokebelow the base of the magazine, where they are virtually consumed beforethe heat passes up into and through the flues D.

In case coal should get fast in the magazine, a poker can easily beintroduced through these openings by which the coal may be loosened andmade to fall.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

rlhe air'openings G in the magazine of a base-burning magazine-stove,when arranged and operating substantially as herein described.

MERRIT'I PEGKHAM.
